AUXILIARY AIR DEVICE.

Application filed April 6, 1918. Serial No. 227,097.

in to the accompanying drawings.

This invention relates to auxiliary air devices and refers moreparticularly to a new and improved construction whereby an auxiliaryamount of either hot or cold air can be supplied to the manifold of aninternal combustion engine.

Among the objects ofthe invention are to provide a control mechanism orvalve which in one position of adjustmentwill connect the valve cylinderto a supply of hot air and in another position of adjustment open it toa source of cold air; to provide a construction which can beeconomically manufactured and conveniently attached to standardconstructions of automobiles; to provide means for adding apredetermined amount of moisture to the auxiliary supply of air; toutilize the auxiliary air device for priming purposes and as a lock;and'in general to provide an improved and simplified construction of thecharacter above referred to.. Y

The inventionalso resides in the particular valve arrangement and insuch further features of construction and arrangements and combinationsof parts as will more fully hereinafter appear.

In the drawings:

Figure l is a diagrammatic elevational view showing a device embodyingmy invention installed in connection with an automobile engine;

Fig. 2 is an enlarged vertical sectional view through the control valve;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2;

Fig. 4 is an enlarged vertical section through the cold air inletopening of the casing;

Fig. 5 is an enlarged sectional view on the line 5 5 of Fig. l.

Describing in detail the particular embodimeiit of my inventionillustrated and reeV ferring first to the general construction shown inFig. 1, A designates an internal combustion engine having an inletmanifold B receiving the explosive mixture from the Specification ofLetters Patent.

sleeved within the casing F andk y with ports M,.M and M2 which controlthey 'Patented Jan." 4, 1921.

carbureter C; D designates the exhaust manifold through which the hotexhaust lgases are discharged through the pipe E.r

1n running internal n combustion engines, particularly those ofautomobiles, it is found that greater: efliciency. can beobtained byysupplying an additionaly amount ofy air` to f the carbureter mixtureunderL certain working conditions of the engine. yForfthis purpose Ihave provided an auxiliary air device comprising a valve casing F,theports of which are controlled by a valve'G. The 01o-y erating stem Gforrotating the valve is ad- ]usted by a leverH which can befextended toyany convenient positionfor operation,

preferably to a position on the dash or steering post. i, f

T he valve port J which is connected by a pipe J to `open to the kairfor receiving a supply fof air at atmospheric temperatures' while athird port-L is connected by a ypipeL to casingF is kprovided with'ria yan air inlet opening under thehot-plate L2 1 which is Lfastened over theexhaust manifold L3. Each of theports are kcontrolled by thevalveG'which, kas shown inFigs. 2 and 3, is formed in the shape of acylinder provided passage 'of air into thek cylinder and also controlthe amount passing through the kauxiliary air device to the manifold.kThe ports M and M2 are preferably ofy a size'to yregister `with themanifold port J and the cold air port K so that a relatively largesupply of cold air can be secured. Upon turning the valve to the left aquarter of a turn the port M2 will register with the hot air i of usingair having an atmos-y of the engineradiator header Q, while the otherend ofthe hollow wire extends be-l neath the hot-plate L2 so that whenthe` valve is adjusted to supply yheated air to ico ics` ythe n d thecarbureter mixture it Will supply air Which contains a greater degree ofmoisture than usual.

In order to permit of a standard size and construction being employedWith cars hav- 111g a capacity for taking a greater or lesser amount ofauxiliary air supply, `there is provided in the branch connection Rleading from the lhot lair port'L a cylindrical member S `having a portS which restricts the hot air opening to a greater or less degree. Byysupplying these auxiliary cylinf ders'which have 4ports of variousdiameters, 'it is possible lto employ one size of valve `casing forengines having .diiferent capaci ties. -lIn such case it is onlynecessary .for the installer to select the cylinder having struction 1K'formed 'on its outer surface so as to receive a small amount of priming*flu-id. I also utilize the auxiliary air device as Va lock forpreventing ltheft vof the CII.

As Shown 'in Fig. 4 the `valve 'G has at fits -upper v'end a flugGwhicli is provided vWith Aan opening .G3 registering with acorresponding yopening F3 ina lug F2 on the casin- F. This Iregistrationof the openings 3 and Fs'takes place When the valve 'G is adjusted tothe position Where the ports M and Mr2 are in full registration with the-ports K and J, -asillust-rated in Fig. 3. It kkhas .been found inpractice that when these ports are in full registration it Will betotally impossible to start the car owing to the excess amount of coldair Which is furnished to the intake manifold. By simply inserting thehasp V of the padlock V vthrough the openings Gr3 and F3 a simple andefficient locking arrangement is obtained.

Various changes, however, in the details of `construction can be madeWithout departing ,from the .scope of my invention.

'What I kclaim vas my invention is l. An auxiliary air device forinternal combustion engines, comprising a casing having an inlet forcold air, an inlet for heated air and a connection with the intakemanifold of the engine, and a cylindrical valve adapted in differentpositions of rotative .adjustment to connect -said cold air inlet :and`said heated air Yinlet to said vintake manifold, said valve and casingbeing providedL with means for lacking the valve with the cold air inletopen to the intake manifold ofthe engine.

2. An auxiliary air device for internal combustion engines, comprising acasing having an inlet for cold air and a connection with the intakemanifold of the engine, a vcylindrical valve having ports adapted in oneposition of adjustment to connect the cold air inlet to the intakemanifold,

said valve and Vcasing having coperating lugs registering when the coldair inlet is fully open, and means engaging said lugs for locking saidvair inlet opening i-n its open position. V

In testimony whereof I afx mysignature.
